Book tracks don't show up

I transferred some book files to my Fuze using WPM10. Media Player told me the synch was successful, and another message tells me that the files are on the Fuze. Problem is that the files don’t show up on the Fuze. Looked in every category but they just aren’t there. Any help would be appreciated.

The tracks need ID3 tags.

Or, update to the latest Fuze firmware as explained hereand under Music you can look for things under Folders, if you know what the folder names were for the books you transferred. That’s a new feature, so you must have firmware version 1.02.26 or 2.02.26 (or, eventually, later versions).
